Mode Conditioning Cable Info. (Mode Conditioning Patch Cord)

The Usage of  Mode Conditioning cable , if you want to apply Gigabit single-mode (LX) over an existing multi-mode fiber Optic Cable Plant.

Things to know when using mode conditioning cables to patch an existing multi-mode cable plant to your Gigabit Single-mode (LX) equipment.

Mode conditioning cable are normally used in pair. That means you need a MC cable at each end to connect the equipment to the cable plant. So then these cables are usually ordered in even numbers. The usual reason why someone may order one cable is for spare unit.

If your gigabit single-mode (LX) switch is equipped with SC or LC connectors, be sure to connect the yellow leg (Single-mode) of the cable to the transmit side, and the orange leg (multi-mode) to the receive side of the equipment. It is imperative that this configuration be maintained on both ends. The swap of transmit and receive can only be done at the cable plant side. (see image below)
Generally, Mode Conditioning patch cords are required for link distances greater than 984 feet (300 meters). We have heard some case stories where that distance has been lesser or greater. To our experience, the distance of 984 feet (300 meters) is just a benchmark. Your results may vary according to various different equipment and field conditions.

Some manufacturers of the newer "high end" multimode fibers claim that that their premium line cables will not require mode conditioning. Contact the manufacturer of your installed cable for the answer.

Propeller Servo Controller USB

The Propeller Servo Controller allows you to control up to 16 servos (32 using two Propeller Servo Controllers) by sending serial commands from a microcontroller or PC via its USB connection. The Propeller Servo Controller USB is Propeller-based and open-source. This means you can modify the existing code or develop your own code to make the Propeller Servo Controller do more and control more.

The Propeller Servo Controller USB is fully compatible with our previous servo controllers and will run with the beta PSCI software application. In addition the hardware and software were set up to take advantage of additional features that you can implement in custom software. Additional features that can be taken advantage of with custom software are an additional 32K EEPROM included for storing of custom settings and/or sequence data, CMOS switch capable of controlling downstream serial communication and a software controlled LED.

Outputs are set at 5V. The Propeller Servo Controller USB contains a superset of the original servo controller commands. Any output can be disabled on startup or set to a custom startup position. Outputs can also be disabled and enabled at any time. The Propeller Servo Controller USB can be powered from a PC USB port or by the host microcontroller.


* P8X32A-M44 Propeller chip on-board
